Each of the storage device has: a storage layer for storing information as the state of magnetization of a magnetic substance; a fixed-magnetization layer having a fixed magnetization direction; and a tunnel insulation layer sandwiched between the storage layer and the fixed-magnetization layer. In an operation to write information on the storage layer, a write current is generated to flow in the layer-stacking direction of the storage layer and the fixed-magnetization layer in order to change the direction of the magnetization of the storage layer. The cell array is divided into a plurality of cell blocks. The thermal stability of the storage layer of any particular one of the storage devices has a value peculiar to the cell block including the particular storage device."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Storage apparatus","description":"Disclosed herein is a storage apparatus including a cell array configured to include storage devices arranged to form an array.
